Hi guys,
Is there any good place to get some nice DMU models?
As tdstead mentioned, i do have some DMUs on my website, primarily KiHa 120 railcars and derivatives. You can find them in the "JR West" and "former JNR lines" sections of my website.
In other news, after a fine summer hiatus, i'm back at modelling Japanese trains, and this time i'll be covering my favourite major private railway, Keio Railway, starting with the 6000 Series!
With 52 individual cars and 56 consists, subdivided into five eras, this one came out as another fat pig of a pack. Hopefully i'll be able to be a little more conservative on the overall variations number next time! :hehe:
Now available on my website!
The 6000 Series was introduced in the early 1970s as the successor of Keio's successful 5000 Series, wich had been built between 1963 and 1969.
The necessity of an entirely new design was due to several factors, primarily the rapid urbanization of the areas served by the Keio Line, with the Tama New Town project in full swing, meant that Keio's trains were getting increasingly overcrowded. New rolling stock was also needed to cover the under-constructions extensions to the Sagamihara Line, to replace the increasingly inadequate pre-war and immediately-post-war built trains such as the 1700 Series and to provide new rolling stock for the planned trough-services between the Keio Line and the under-construction Toei Subway Shinjuku Line.
The latter became the basis of the new design, with Keio abandoning the 18m-long bodyshell with three doors to finally adopt the standard 20m-long bodyshell with four doors. Other design fetaures were requirement of the stringent subway regulations, wich mandated a front door to be used as an emergency exit and the exclusive usage of non-flammable materials.
Among other things, the 6000 Series was also Keio's first train to adopt the iconic T-shaped master controller, wich had been introduced only a few years earlier by Tokyu railway.
The first six trains were delivered to Keio in 1972, having been built by Tokyu Car Co. (for the cab cars) and by Hitachi (for the intermediate cars). A peculiarity of these trains was that the cab cars had different air conditioning units from the intermediate cars - Tokyu had used four small conditioners, as was the praxis for the rolling stock built for it's parent company, Tokyu Railway, instead of a single, centralized one as was on the Hitachi-built cars.
An additional batch of six six-car sets was delivered a year later in 1973 - depsite the similar looks, these actually differed slightly from the earlier batch in several ways: first of all, the air conditioners on the cab cars were standardized to the centralized unit of the intermediate cars, the livery was simplified (the dark red band being no longer pointy towards the central door, but keeping instead the same height) and the traction control system was changed from the camshaft resistor control derived from the earlier 5000 Series to an up-to-date shunt-chopper control.
In 1975 8-car 6000 Series sets were introduced for the first time, with 12 intermediate cars being delivered to lenghten the 1972-batch trains to eight cars.
This coincided with the start of 6000 Series assignments to Limited Express services on workdays - until then the 6000 Series had only been used on "normal" Express services, with Rapid and Local services being still exclusive assignments of the 5000 Series and previous "green trains" such as the 2000 Series.
This was due to the short lenght of many platforms of stations served only by Local trains, still designed for six-car trains of 18m-long cars, hence the 6000 Series, with it's 20m-long bodyshell couldn't fit in most platforms.
This was solved in 1976, with the introduction of 5-car and 3-car sets, wich were to act as stop-gap local trains until all platforms could be lenghtened (a 5-car train with 20m-long cars needs roughly the same platform space as a 6-car train with 18m-long cars). The 5-car sets operated on local services, but could be coupled to the 3-car sets to form an 8-car set for Express and Limited Express services.
A few years later, with the impending completion of the Toei Shinjuku Line and the start of trough-services with the Keio Line (via the aptly-named, newly-built Keio New Line), a new batch of fourteen 8-car sets, officially known with the seldom-used name of "6030 Series" were delivered to Keio between late 1978 and mid-1979. These were designed entirely around subway trough-services and as such fetaured some adaptations and modifications, such as being fitted with the Shinjuku Line's ATC system and a new "ground-to-train" radio.
Reciprocal trough-services with the Toei Shinjuku Line finally commenced in March 1980, with Keio 6000 Series trains now running beyond Shinjuku, altough initially only as far as Iwamotocho, as the platforms east of it were long enough only to accomodate 6-car trains (wich was then the standard lenght of Shinjuku Line trains). Shortly after, with the further eastwards extensions of the Shinjuku Line, the platforms were likewise lenghtened, allowing Keio trains to finally run the whole of the Shinjuku Line, from the namesake Shinjuku all the way to the eastern terminus of Motoyawata.
1981 saw the introduction of 2-car sets, these being designed to extend 8-car trains to 10-cars and 6-car trains to 8-cars during rush hours. A total of eighteen was built between 1981 and 1989, with seven of them being part of the 6030 Series and thus cleared for trough-services on the Shinjuku Line, and 11 being intended for the Keio network only.
Three additional 8-car sets were delivered between 1988 and 1990 to cover the last extensions of the Sagamihara Line, from Keio Tama-Center to Minami-Osawa and Hashimoto, opened in May 1988 and March 1990.
In 1989 the new "
KEIO" company logo was introduced, being subsequently applied to the railway's trains, with the 6000 Series being no exception - in this case, the new logos replaced the car numbers on the side, between the cab door and the first passenger door.
In 1991 the final, and most peculiar batch of the 6000 Series was introduced: four 5-car trains with five doors per side instead of the standard four were delivered to Keio railway between February and March 1991. These were intended to reduce congestion on the notoriously-saturated Keio line by speeding-up dwell time (boarding and alighting) on local services at stations that did not have passing loops. Starting from 1992, a front skirt was added to all trains.
